An enantioselective fluorination of allylic alcohols under chiral anion phase-transfer conditions is reported. The in situ generation of a directing group proved crucial for achieving effective enantiocontrol. In the presence of such a directing group, a range of acyclic substrates underwent fluorination to afford highly enantioenriched α-fluoro homoallylic alcohols. Mechanistic studies suggest that this transformation proceeds through a concerted enantiodetermining transition state involving both C–F bond formation and C–H bond cleavage.

烯丙醇手性阴离子相转移氟化的原位指导组策略



报道了在手性阴离子相转移条件下烯丙醇的对映选择性氟化。事实证明,原位生成导向基团对于实现有效的对映体控制至关重要。在这种导向基团的存在下,一系列无环底物发生氟化,得到高度对映体富集的α-氟高烯丙醇。机理研究表明,这种转变通过协调的对映决定过渡态进行,涉及 C-F 键形成和 C-H 键裂解。
